如果你知道往哪裡看,就能看到一顆白矮星的熱核爆炸。可能是兩次。 這種爆炸被稱為新星,目前在地球的南半球,用肉眼可以隱約看到爆炸--但用雙筒望遠鏡更容易看到。圖為上週在銀河系中心平面附近拍攝到的狼 2025 新星(V 462 Lupi)。 狼新星 2025 最初是在 6 月 12 日被發現的,大約一週後亮度達到頂峰。同樣,船帆座(Vela)南側的 2025 號新星也是在 6 月 25 日被發現的,幾天後亮度達到頂峰。 銀河系中某處的新星每隔一兩年才會被肉眼短暫觀測到,因此同時觀測到兩顆新星是很不尋常的。 與此同時,人類還在等待著另一顆新星:北冕星,它應該會在北方的天空中出現,而且預計會變得更加明亮。
原文:If you know where to look, you can see a thermonuclear explosion from a white dwarf star. Possibly two. Such explosions are known as novas and the detonations are currently faintly visible with the unaided eye in Earth's southern hemisphere -- but are more easily seen with binoculars. Pictured, Nova Lupi 2025 (V462 Lupi) was captured toward the southern constellation of the Wolf (Lupus) last week near the central plane of our Milky Way galaxy. Nova Lupi 2025 was originally discovered on June 12 and peaked in brightness about a week later. Similarly, Nova Velorum 2025, toward the southern constellation of the Ship Sails (Vela), was discovered on June 25 and peaked a few days later. A nova somewhere in our Galaxy becomes briefly visible to the unaided eye only every year or two, so it is quite unusual to have two novas visible simultaneously. Meanwhile, humanity awaits even a different nova: T Coronae Borealis, which should become visible in northern skies and is expected to become even brighter.
